# The difference between this PKGBUILD and the one from `emacs-git` is that:
|
||
|
|
# - this one builds emacs from `emacs-27` release branch.
|
||
|
|
# - link-time optimization and use of clang are disabled by default.
|
||
|
|
#
|
||
|
|
# It hence should be more stable and less frequently updated than `emacs-git`.

# CAVEAT LECTOR: This PKGBUILD is highly opinionated. I give you
|
||
|
|
# enough rope to hang yourself, but by default it
|
||
|
|
# only enables the features I use.
|
||
|
|
#
|
||
|
|
# TLDR: yaourt users, cry me a river.
|
||
|
|
#
|
||
|

# Everyone else: do not update blindly this PKGBUILD. At least
|
||
|
|
# make sure to compare and understand the changes.
